Scaling Behavior of Inclusive Pion Electroproduction

Abstract

We report new measurements of inclusive pion electroproduction. Data were taken with deuterium and hydrogen targets at the $W$ and $Q^2$ points (2.15 GeV, 1.2 Ge${\mathrm{V}}^2$), (2.15, 4.0) and (3.11, 1.2) and with only hydrogen at (2.15, 2.0), (2.67, 0.6), (2.67, 1.2), (2.67, 2.0), (2.67, 3.3), and (3.11, 1.7). The invariant structure function and the $\frac{{\pi }^{+}}{{\pi }^{-}}$ ratio are studied as a function of $Q^2$, $W$, and $\omega$.
